Why Proof of Funds Matters for Crypto Buyers

How proof of funds reduces friction, builds trust, and prevents wasted time in high-value crypto transactions.

In traditional finance, proof of funds is a standard requirement. In crypto, it’s often missing — and that gap causes friction, mistrust, and failed deals.

Whether you’re buying real estate, entering an OTC trade, or negotiating a private sale, being unable to quickly prove liquidity can slow everything down.

The problem with “just trust me”

Crypto holders are used to self-custody and privacy, but counterparties often need reassurance:

  • Landlords need confirmation before approving applications
  • Sellers want to avoid time-wasters
  • Brokers must validate buyer credibility

Asking someone to share a wallet address or screenshots is clumsy, insecure, and easy to fake.

What proof of funds should look like

A modern proof of funds solution should be:

  • Verifiable – backed by on-chain data
  • Privacy-preserving – no private keys or transaction history exposed
  • Time-bound – valid for a limited window
  • Professional – suitable for banks, landlords, and brokers

This is where wallet-based verification changes the game.

The WalletSign approach

WalletSign allows crypto holders to generate a one-time verification link that confirms balances across supported chains and produces a verifiable PDF with a QR code.

The recipient doesn’t need to understand crypto — they just scan and verify.

When proof of funds makes the biggest difference

  • Real estate applications
  • OTC crypto trades
  • Business acquisitions
  • Private lending
  • High-value asset purchases

If crypto is going to be taken seriously as capital, proving funds needs to be as simple as sharing a bank statement — without sacrificing privacy.


Proof of funds isn’t about showing off wealth. It’s about reducing friction and building trust.
